Sigma NAD 18-200/3.5-6 II DC OS HSM
 
The Sigma Corporation is pleased to announce the release of the
SIGMA 18-200mm F3.5-6.3 II DC OS HSM.
This 11.1x high zoom ratio lens is designed exclusively for digital
SLR cameras, incorporates Sigma’s original
OS (Optical Stabilizer) function and offers a broad shooting range from
wide angle to telephoto.
The SIGMA 18-200mm F3.5-6.3 II DC OS HSM is the successor
to the SIGMA 18-200mm F3.5-6.3 DC OS/ HSM
which was launched in June 2007. The lens is ideal for travel
photography with a compact construction and length of just 87.7mm.
This lens features FLD (“F” Low Dispersion) glass elements, which
have the performance equal to fluorite glass, and SLD
(Special Low Dispersion) glass elements providing excellent correction
of color aberration. Aspherical lenses give excellent correction for
all types of aberration and distortion. The Super Multi-Layer Coating
reduces flare and ghosting, ensuring high quality images throughout
the entire zoom range. Sigma’s OS (Optical Stabilizer) system offers
effective correction of approximately 4 stops, enabling easy handheld
photography. HSM (Hyper Sonic Motor) ensures quiet, high-speed
auto focus and the inner focus system eliminates front lens rotation,
making the lens particularly suitable for using the supplied petal-type
lens hood and circular polarizing filters. The rounded 7 blade diaphragm
creates an attractive blur to the out of focus areas of images.
Sony and Pentax mounts do not incorporate Optical Stabilization.
